Description

Technical Field

[0001] The utility model relates to the technical field of magnetic pipe cutting machines, and more specifically to a novel magnetic pipe cutting machine. Background Art

[0002] The magnetic pipe cutting machine has two groups of four permanent magnetic wheels, which automatically surround the steel pipe for cutting through a transmission mechanism. When using this cutting machine to cut the pipe, the efficiency can be improved, the quality can be guaranteed, and the labor intensity can be reduced.

[0003] After searching, the existing patent (Announcement No.: CN211101834U) discloses a magnetic pipe cutting machine that is easy to clean. When in use, the protective cover can effectively block the iron chips generated during the cutting process in the protective cover to prevent the hot iron chips from splashing out and possibly causing harm to personnel. The movement of the cutting machine body is driven by the motor in the motor box, which not only saves time and effort, but also greatly improves the safety of operation. The roller brush is driven by a belt, and the rotation of the roller brush will clean up all the iron chips around the magnetic pulley. The entire roller brush is evenly distributed with brushes of the same specifications to prevent iron chips from adhering to the magnetic pulley and reduce the magnetism of the magnetic pulley, making it easy to observe the status of equipment and pipelines during work and to facilitate maintenance. However, in the process of realizing the utility model, the inventor discovered that the prior art had the following problems: in the above-mentioned magnetic pipe cutting machine, when the cutting gun is used, the angle of the cutting gun is fixed and always perpendicular to the bottom of the cutting machine. In this way, when the pipe is cut, the cross-section of the pipe is a water surface slope. When the pipe needs to be connected and installed later, it is often necessary to process the cross-section of the pipe into a tapered surface. The horizontal cross-section of the pipe is not conducive to the subsequent processing of the conical surface of the pipe, and its use has the defect of low adjustment adaptability.
